TO ALL WHOM IT MAY CONCERN:

Be it known that I, RICHARD UREN, of. Houghton, in the county ofHoughton, and State of Michigan, have invented a new and improved CopperOre Washer; and I do hereby declare that the following is a full, clear,and exact descriptionthereof, reference being had to the accompanyingdrawings, forming part of this specification.

The nature of my invention consists in washing ores or minerals bycausing them to flow across a revolving helt,.by which means the ores ofminerals may be thoroughly washed and the earth be entirely removedthere from. It more particularly consists in constructing a frame inwhich run pulleys, and a wide belt, upon which the ore is deposited froma deflecting board, and upon which aflow 'of water is also admitted tothe bel-t from a deflecting board. Various devices have been introducedfor the purpose of washing ores, but have proved unsatisfactory and ofbut little account, failing, in a great measure, of performing the workfor which they were designed. But by my invention I am enabled toobviate all of the difficulties encountered by other devices used forthis purpose. To enable others skilled in the art to make and use myinvention, I will proceed to describe its construction and operation.

Figure 1 is a top plan view of my improved ore-washingmachine.

Figure 2 is a transverse sectional elevation of the same from the line mx.

Letters of like name and kind refer to like parts in each of thefigures.

A is the frame of my improved apparatus for washing ores, made of wood,and of any desired dimensions suitable for the amount of work desired tobe done. 13 is a wide belt reaching from one side of the frame A to theother, entirely filling the space between the posts-of the frame. Thisbelt 13 runs over pulleys or drums, C C, which are provided withjournals that run in proper bearings secured to the frame A. L is adeflecting board extending longitudinally from end to end of the frameA, and secured thereto by any proper means. F is also another deflectingboard, and extending the whole length of the frame, and upon which oneedge of the belt B runs. G is a box or spout locatedat the side of theframe A, and immediately under the edge of the deflecting board F. I Iare tubes or pipes, one of which extends through thebox S into the boxS, while the other only extends into the box S. J is a pulley secured tothe shaft 0, to'which poweris applied to' drive the machine.

i The operation is simple and perfect. Power being applied to the pulleyJ, the machine or belt Bis driven in the direction of the arrow, and theore is placed upon the deflector E, ;and is spread out upon the belt B,while a stream of water is made to flow down the deflector D, upon thebelt B. Now it will be seen that the belt 13 descends from thedeflectors E and D toward the deflecting board F and box Gr, so that agreat portion of the water and heavier ores run off into the box G,while the balance is carried by the belt B, and deposited in the boxes Sand S, in which is kept a supply of water from the belt, and whichpasses oifthrough the eduction tubes or pipes I I. H H H H are feet uponwhich the machine stands.

Having thus described my invention, what I claimas new, and desire tosecure by Letters Patent of the United States, is 7 Washing ores orminerals by causing the same to flow across a revolving belt,substantially and for the purposes described.

The above specification of my invention signed by me this day of 1866-RICHARD UREN.
